The NFL is investigating a Steelers assistant coach for allegedly kicking a Patriots fan

James Daniel, the Pittsburgh Steelers' tight ends coach, is under
NFL investigation for allegedly "assaulting and verbally
accosting" a New England Patriots fan on Thursday night during
halftime on the way to the locker room,
ESPN's Adam Schefter reports.

Daniel allegedly kicked a Patriots fan in the back of the leg and
screamed at him during halftime.

Writes Schefter:

By the time Daniel returned to the coaching booth after halftime,
police and NFL security were waiting for him. Once the coach was
identified by witnesses, and police approached him about
controlling his behavior, Daniel began shouting at the police
officer, according to witnesses.

NFL security, which did not witness the exchange with police,
interviewed Daniel afterward about the entire incident, according
to sources.
